Accept some stolen Dürers (6)
I believe the answer is:
'accept' is the definition.
(I know that accept is a more specific form of the action endure)
'some stolen durers' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ENDURE' is hidden within 'stolen durers'.
(Other definitions for endure that I've seen before include "Bear, stick it out" , "Last or suffer patiently" , "Remain in existence; suffer" , "survive" , "'Last, bear (6)'" .)
